I RlDlNG-HARROW.

SPECIFICATION forming part of Letters Patent No. 789,263, dated May 9, I905.

Application filed November 14:, 1904:. Serial No. 232,701.

To all whom it may concern.-

Be it known that I, REUBEN C. DENNIs, a citizen of the United States, residing near Perry, in the county of Monroe and State of Missouri, have invented a new and useful Riding-Harrow, of which the following is a specification.

This invention relates to harrows, and more particularly to riding or sulky harrows, consisting of harrowframes connected with wheel-supported supporting-frames in such a manner that thesaid barrow-frames may be raised or lowered, as may be desired by the operator.

The object of the invention is to simplify and to improve this class of devices and to provide means whereby harrows may be suspended from a supporting-frame and whereby the said harrows may be raised or lowered in a convenient, rapid, and eflicient manner.

With these and other ends in View, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and. combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes and modifications may be made within the scope of the invention and without departing from the spirit or sacrificing the efficiency. of the same.

In said drawings, Figure 1 is a perspective View of a riding-barrow constructed in ac cordance with the principles of the invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a longitudinal sectionalview.

Corresponding parts in the several figures are indicated by like characters of reference.

The supporting-frame of the improved harrow is rectangular in shape and is composed of side pieces 1 1 and the front and rear crosspieces 2 3. Said front and rear cross-pieces support a tongue 4, which is bolted securely in position and at the rear end of which is mounted aspring-bar 5, supporting the seat 6.

The front and rear cross-bars 2 3 of the main frame support a pair of longitudinallydisposed triangular castings 7, which are provided with longitudinally-extending lugs or brackets 8 S, resting upon the cross-bars of the frame, with which they are-connected by means of bolts or other fastening means 9. The apices of these triangular castings or brackets extend downwardly between the sides of the frame and are providedwith bearings for the shafts of the supporting-wheels 10, which are journaled tosaid brackets. The

upper sides of the brackets 7 are provided' with segment-racks 11, which may be cast or formed integrally therewith, and concentrically with said brackets are fulcrumed the hand-levers 12, having springactuated dogs or pawls 13 of ordinary construction which engage the segment-racks for the purpose of retaining the levers in adjusted position. The levers. 12 are provided at their lower ends withcrank-arms 1.4.

In the example of the invention which has been illustrated in the'drawings two separate barrow-sections are provided, each being designated 15. Said barrow-sections are composed of spaced longitudinal bars 16, spacing members 17 at the front ends of said longitudinal bars, cross-pieces 18, connecting and spacing the rear ends of said longitudinal bars, obliquely-disposed tool-carrying bars 19 19, and braces 20. The longitudinal harrow-bars 16 are spaced apart sufficiently in each barrow-section to accommodate one of the wheels 10 and the triangular casting or bracket upon which the wheel is ournaled. Said side bars 16 of each harrow-section are connected by means of a yoke 21, straddling the wheel and the bracket or casting and con nected pivotally with the crank-arm 14 of one of the adjusting-levers.

I-Iingedly connected with the longitudinal bars 16 of each barrow-section is a draft member 22, consisting of a yoke the ends of the arms of which are provided with loops 23, engaging staples 24 upon the barrow-bars. The yokes 22 are provided with forwardlyextending arms 25, extending through guideloops 26, connected with and depending from the front bar 2 of the supporting-frame, said arms being provided at their front ends with loops 27 for the attachment of the draft. The draft, it will thus be seen, is attached direct to the harrow-sections, but at a point which is sufficiently elevated to prevent the swingletrees from striking the heels of the draft-animals.

From the foregoing description it will be readily understood that by manipulating the levers 12 the harrow-sections may be raised or lowered to any extent that may be deemed desirable or necessary. When the harrowsections are lowered, they will be held positively in the ground and will not be capable of being dragged clear of the ground when draft is applied. The Wheels and the casting or brackets to which the wheels are ournaled will not interfere with the raising of the harrow-sections, which may be lifted, if desired, to a point almost directly under the supporting-frame, which is obviously desirable and convenient when the harrow is to be moved from oneplace to another. I

The general construction of the device is simple and inexpensive and of such a nature as to insure the greatest amount of strength and durability.

Having thus described the invention, what is claimed is 1. In a riding-hairow, a supporting-frame, longitudinally disposed wheel supporting brackets having lugs secured upon the front and rear cross-bars of said frame, and vertically-adjustable harrow-sections straddling the wheels and supporting-brackets.

2. In a riding-harrow, a supporting-frame, longitudinally disposed wheel supporting brackets having lugs secured upon the front and rear cross-bars of said frame, and vertically-movable barrow-sections having longitudinal frame-bars spaced apart to accommodate the wheels and supporting-brackets.

3. In a riding-harrow, a supporting-frame, longitudinally disposed wheel supporting brackets having lugs secured upon the front and rear cross-bars of said frame, verticallymovable harrow-sections having longitudinal frame-bars spaced apart to accommodate the wheels and supporting-brackets, yokes connected with said frame-bars and straddling the wheels and supporting brackets, and adjusting-levers having arms connected with said yokes.

4. In a riding-harrow, a supporting-frame, longitudinally disposed Wheel supporting brackets having lugs secured upon the front and rear cross bars of said frame, vertically movable harrow-sections, yokes connected with said harrow-sections and straddling the wheels and supporting-brackets, and adjusting-levers pivoted to the supporting-brackets and having arms pivotally connected with the adjusting-yokes.

5. In a riding-harrow, a supporting-frame, longitudinally disposed wheel supporting brackets having lugs secured upon the front and rear cross-bars of said frame and having rack-segments upon their upper sides, adjusting-levers pivoted to the brackets and having dogs engaging the racksegments,ver tically-movable harrow-sections, and yokes connected with said harrow-sections, straddling the wheels and supporting-brackets, and connected pivotally with crank-arms of the adjusting-levers.

6. In a ridingharrow, a supporting-frame, provided at its front end with depending guide-loops, Wheel-supporting brackets connected with said frame, levers connected with said brackets, verticallymovable harrowsections, yokes connected with said harrowsections and having pivotal connection with the adjusting -levers fulcrumed upon the wheel-supported brackets, and draft members connected hingedly with the harrowsections and extending through the guideloops depending from the supporting-frame.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

REUBEN C. DENNIS.
